HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,677, datedSeptember 10, 1889.

Application filed December 16, 1836- Serial No. 221.702. (No model.)

To all whom it may concern.-

Be it known that I, FREEBOEN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex, and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Heel-Nailing Machines, ofwhich the following is a full, clear, and eX- act description, referencebeing had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The invention relates to a heel-attaching machine having heel-edgemolding or forming devices for forming or molding the edge of the heelbefore it is attached to the soles of the boot or shoe.

It further relates to mean s for automatically feeding heel-blanks tothe said heel-forming devices and for transferring them therefrom to theheel-blank-attaching devices.

It further relates to various details of organization and construction,which will hereinafter appear.

In the drawings, Figure 1 is a view in vertical cross-section of amachine containing the features of my invention. Fig. 2 is a view invertical section taken from front to back of the machine to furtherillustrate its construction and operation. Figs. 3, Al, and 5 are detailviews.

A is the cross-head, and a the revolving head, which is adapted to beautomatically revolved, and which has an arm carrying a gang or group ofawls, another arm carrying a gang or group of drivers, and still anotherarm carrying a top-lift-breasting device.

A is the templet; A the nail -carrier; A the last or work-support; a,the jack; a the spindle or rod supporting the work-support; A*, thetoggle-head, which is operated similarly as described in my previousinventions.

A is the top-lift-carrier plate, which is in all material respects likethat described in said previous inventions, which receives top lifts andis adapted to be operated as therein described.

A is the heel-blank-transferring plate. It is also substantially likethat described in said inventions, and is operated or movedsubstantially as therein specified.

The heel-blank-edge molding or forming devices comprise a pocket B,which is arranged below the level of the heel-blank-t-ransferring plateA, and which is formed by the movable head I) and thehorizontally-moving forming-jaws Z) 11 b The heel-blank is fed to thepocket B when the heel-blank-transferring plate A has been moved inwardto transfer or move a heel-blank under the templet, and I prefer to holdthe heel-blanks in stack in the box 0 and to feed them one by one to thepocket 13 by the carrier 0, which is operated at intervals to transfer ablank from the stack to the pocket, as described in my said inventions.

The forming-jaws 'b' b b b are adapted to have radial movements, ormovements substantially radial, and upon a substantially horizontalplane, and they are operated to close simultaneously upon the verticaledge of the heel-blank and to compress it solidly by lateral presssureagainst the front wall I) of the pocket. I have represented the sidepressers as provided with these movements by means of the levers B B B Bthe lever B carrying the jaw Z), the lever B carrying the jaw b thelever 13* carrying the jaw b and the lever B carrying the jaw b. Eachjaw, preferably, is attached to its respective lever by means of adovetail joint, and so as to be readily removed therefrom, (see Fig. 4,)and each is locked in place by alocking-screw Each lever is pivoted to asupport or arm at b, and the lower ends of the levers carry rolls bwhich are adj ustably secured to the ends of the levers and are arrangedto bear upon the inclined surfaces 17 of the slide-head D, so that uponan upward movement of the slide-head D the jaws are caused to be closedor moved inward. Upon the downward movement of the slide-head D the jawsare opened by the springs b,which bear against the outer edges of thelever.

The slide-head D carries the lower head or heel-seat former b, and it isprovided with a vertical movement, preferably by means of the cam-leverE, which is pivoted at e, and has the cam-groove e,wl1ich receives thecam-pin e extending-from the slidehead. The lever also has the arm 6which is adapted to be moved by a cam-groove e in a cam-disk e upon thecamshaft e or by an eccentric on the crank-shaft. (Not shown.) It willbe seen that by this construction the upward movement of the slide-headD, and consequently of the lower head 1), upon which the heel-blank isfed from the stack, causes the heel-blank to be moved upward, and at thesame time the jaws to be closed upon its edges with very great pressure,and at the same instant another head F, attached to or carried by thecross head A, moves downward, and its under surface enters the spacebetween the jaws and acts as an abutment to resist the upward thrust ofthe lower head I), so that the heel is molded not only by lateralpressure exerted against its side edge, but also by vertical pressureexerted against its under surface, and it is thereby not only compactedvery solidly, but is also brought to a molded shape, I

or a shape which approximates the shape of the finished heel.

This treatment of the heel-blanks is especially applicable toheel-blanks made from pieces, or-known as pieced heels.

The extent of the inward movement of the jaws b b b b is varied by meansof the ad j ustable rolls b at the lower ends of the operating-levers.If the rolls are set out in re lation to the ends of the levers, thenthe jaws are moved inward. If they are set closer to the ends of thelevers, then the jaws are not moved inward so far, and in this way adjustment to varying sizes of heels is obtained.

After the heel has been formed it is necessary to remove it from thejaws, in order that it may be carried or transferred to theheelattaching devices. This is accomplished by making the lower head I)movable in the slidehead D, so that upon the downward movement of theslide-head 1D after the compression of a heel-blank and the opening ofthe jaws b b b b the head I) is caused to be moved upward between thejaws to move the heel-blank above the upper level or surface of thejaws, and so as to be taken by the transferrer-plate A and advanced tothe heel-attaching devices. This movement is given the head I) by meansof the rod G, which is provided witha vertical movement in theslide-head D and to the end of which the head I) is attached, and alsoby means of the lever g, the end g of which receives the lower end ofthe rod G, and at its opposite end to a rod giwhich connects it with acam g The cam is so timed as to cause the rod G, and therefore thecompressed heel, to be lifted immediately before the transferrer A iscaused to be moved forward to feed or transfer the heel-blank.

In use the heel-blank is fed from the stack or receptacle to theheel-molding devices and the heel-molding devices then caused to beoperated to mold the heel-blank. These operations are proceedingsimultaneously with the attaching of a previously-molded heelblank tothe soles of a boot or shoe. The molded heel-blank is then moved fromthe molding devices to the transferrer, which engages it and feeds it.

The advantages of the invention arise from the fact'that the heel-blankis molded immediately before it is attached to the soles of the boot orshoe to which it is to be secured and as an automatic operation, theheelblank being delivered to the molding devices and molded and thentransferred to the heelattaching devices and attached automatically orwithout handling.

I am aware of Patents No. 112,702, to Glidden, No. 153,360, to McKay andFairfield, and No. 246,945, to Fischer; but I consider that thesepatents do not contain the features of myinvention, because they do notdescribe the embodiment in an organized nailing-machine of theseelements-namely, a heelcompressing device for molding the side edge of aheel-blank and a heel-attachin g device for attaching the molded heel tothe soles of a boot or shoe adapted to have conjoint and simultaneousact-ion upon two distinct heelsand because they do not show, nconnection with these appliances arranged 1n an organized machine forconjoint action, the heel blank feeding mechanism adapted to feedheel-blanks to the heel-edge-molding devices and transferring mechanismadapted to carry the molded heel-blank from the moldin g devices to theheel-attaching devices.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In an organized heel-nailingmachine, the combination, with heel-attaching devices, of aheel-blank-edge molding or compressing apparatus consisting of verticaland lateral formers or pressers from which the blank 1s automaticallytransferred to said attaching I devices connected substantially asdescribed and automatically operated, and thereby adapted for conjointand simultaneous use, one to mold the side edge of a heel-blank: and theother to attach apreviously-molded heelblank, substantially asdescribed.
